tember 16, 1890, wherein circulating matrices are released from amagazine in the order in which their characters are to appear in printand then composed in line, the composed line presented to the face of amold, the mold filled with molten metal to form a printing slug againstthe matrices which produce the type characters thereon, and the matricesthereafter returned through distributing mechanism to the magazine from.whence they started. More particularly, the invention is directed tocertain improvements which adapt these machines, when so desired,automatically to cast a predetermined plurality of desired slugs, suchimprovements being herein presented in the nature of an attachment whichcan be applied substantially to all commercial machines with practicallylittle or no alteration.

As is well known, the means for presenting the composed line to the moldincludes a transporter or so-called first elevator which descends toposition the line between a pair of clamping jaws for linejustification, and after the casting operation ascends to permittransfer of the line to the second elevator from which the matrices passto the distributing mechanism. Also as is well known, one of theclamping jaws is fixed (except for a limited movement to operate thecustomary pump stop) and the other (usually the left-hand jaw) isadjustable to different positions to accord with the length of the moldslot or the length of the composed line in its justified condition, theposition of such adjustable jaw being determined by an adjustablebanking stop which, however, does not interfere with the free movementof the jaw against the relatively fixed jaw in the absence of a matrixline between them.

In carrying out the present invention in its preferred embodiment(although the invention is not limited to such embodiment as will laterappear), mechanism is provided operating automatically to inaugurate apredetermined number of cycles of operation; to prevent the transfer ofthe line from the first elevator during a predetermined number of cyclesof operation so that the same line is presented a plurality of times tothe mold to cast a corresponding plurality of duplicate printing slugs,and other mechanism provided likewise operating automatically duringother predetermined cycles of operation of the machine for moving theleft-hand clamping jaw into contact with the right-hand clamping jaw toclose the mold completely at one side so that blank slugs may be cast inthe mold against the face of the left-hand clamping jaw during suchcycles.

The invention also contemplates the provision of an improved galleyassociated with the casting mechanism and formed with a plurality ofcompartments for holding the slugs delivered from the casting mechanismin separate columns, the galley also having mechanism associatedtherewith for automatically separating and stacking duplicate slugs asthey are delivered therein.

Among other uses, the invention is of special utility in the productionof slugs employed in advertising or telephone book work, wherein it isfrequently desirable to use duplicate printing slugs alone or incombination with blank slugs, the blank slugs being used to supportoverhanging portions of the printing slugs.

For a clear understanding of the invention, reference may be made to theaccompanying drawings wherein the invention is shown merely by Way ofexample and in preferred form. Ob viously, however, many variations andmodifications may be made therein which will still be comprised withinits spirit and it is to be understood, therefore, that the inventionisnot limited to any specific form or embodiment, except in so far as suchlimitations are specified in the appended claims.

In the operation of the machine in the customary manner, that is to say,to produce a single printing slug from each composed line, the matricesare released from their storage magazine by a keyboard mechanism and aredelivered to and composed in line in the assembling elevator [3 which isthen manually elevated to raise the composed line between the dependingfingers l4 and !5 ofthe line delivery slide it which thereupon transfersthe line from the assembling elevator 13 through the intermediatechannel I! to the line transporter 0r first elevator l8. Upon receivingthe line, the line transporter l8 descends to position the line betweenthe lefthand clamping jaw I9 and the right-hand clamping jaw 20 (bothjaws being mounted on and carried by the vise frame 2|) in front of thethen horizontally positioned slotted mold 22 on the mold carryingmovable element or mold wheel 23 (the latter having previously beengiven a one-quarter turn to carry the mold in use from its verticalejecting position to its horizontal casting position). The line is thenjustified, and the mold Wheel 23 advanced from its rotating position topress the mold 22 into contact with the matrix line and the two clampingjaws l9 and 20 which constitute a closure for the front face of the moldagainst which the slug is cast in the usual manner. After the slug hasbeen cast the mold wheel 23 is carried back to its rotating position androtated through the remaining three-quarter revolution necessary torestore the mold to its vertical position. The mold wheel 23 is thenadvanced again from its rotating position to carry the mold 22 againstthe knife block 24 (Fig. 2), after which the ejector 25 is advanced toforce the slug out of the mold, through the knife block and into thegalley 26; and finally, at the completion of a machine cycle ofoperation the mold wheel 23 is again carried back to its rotatingposition.

After the slug has been cast the line transporter I 8 carrying thejustified line ascends to its uppermost or line transfer position inwhich position the stop member 21'! carried by the line transporter isabove the transverse stop. member 28 carried by the line transfer slide29, .thereby permitting the line to be shifted therefrom through theupper transfer channel 30 onto the second elevator bar (not shown) whichdelivers them to the distributing mechanism, whereby they are returnedto their proper channels in the storage magazine from whence theystarted.

As is well understood in the art, the various parts referred to, withthe exception of the assembler l3 which is under manual control, areoperated from the main drive shaft of the machine which is caused tomake one complete revolution for each cycle of operation, the main driveshaft being driven by an electric motor through a spring actuated clutchwhich is thrown into action by a trip dog carried by a cam fast to themain drive shaft.

While in the normal operation of the machine the clutch is automaticallythrown into action on the release of the delivery slide it is also undermanual control, there being provided for this purpose a train ofconnections leading from the trip dog and including a forwardly andbackwardly reciprocating clutch control bar 3|, the forward end of whichis pivotally connected by links 32 and 33 to a hand lever 34. The handlever 34 is provided with a bifurcated hub portion 35 rotatably mountedon a vertical shaft 36 which normally is fixed in lugs 31 and 38 carriedby a bracket 39 secured to the main frame of the machine. By thisarrangement, when the hand lever 3| is swung backwardly from its neutralposition, the spring actuated clutch is locked in its inactive positionand when the hand lever is swung forwardly from its neutral position theclutch control mechanism operates the clutch and the machine is started.The details of the clutch control mechanism are fully shown anddescribed in U. S. Letters Patent No. 661,386, granted to J. R. Rogerson November 6, 1900, and being so well known, they do not require anyfurther description here.

While the above briefly describes the various parts and their mode ofoperation in producing a printing slug during a machine cycle ofoperation, such machines are sometimes provided with means which permitblank slugs to be cast during other cycles of operation, and in suchcases the left-hand clamping jaw I9 is utilized to close the front faceof the mold 22 during the machine cycles of operation it is desired tocast such blank slugs. banks against a manually adjustable stop on thevise frame 2| and thus determines the length of the justified matrixline but it is movable from this adjusted position up against theright-hand clampingjaw28 when no matrix line is present, and in theembodiment illustrated such movement is effected by mechanism actuatedautomatically by the mold wheel 23 as it rotates during a machine cycleof operation. The particular mechanism il- Normally, the lefthandclamping jaw l9 lustrated for actuating the left-hand clamping jaw 19comprises a Geneva stop motion device consisting of Geneva disk or plate40 rotatably mounted on the vise frame by means of a horizontal stud 42carried by a bracket 43 which is screwed or otherwise secured to thevise frame. The disk lit is formed at four equi-distant points at itsperipheral edge with radial slots 44; and fixed to the face of this diskis a cam plate 45 which, in the rotation of the disk, is adapted toengage a roller 45 mounted on the lower end of a vertically arranged jawactuating lever 4'1 pivoted between its ends by a pin 48 to a lug 49projecting from the bracket 33, the upper arm of the lever being pivotedto a horizontal link 50 which is, in turn, pivotally connected to theleft-hand clamping jaw it. The Geneva disk #0 is rotated by means of apin 5! carried by the mold wheel 23 and projecting forwardly from thesame near its peripheral edge, the pin 5| in the successive rotation ofthe mold wheel 23 entering and leaving slots M in the Geneva disk 40 insuccession and thereby imparting one-quarter rotation to the disk ateach complete rotation of the mold wheel 23. In such rotary movements ofthe Geneva disk two blank slugs.

46, the cam 45 by engaging the roller 46 on the lower arm of the jawactuating lever 4'5, will shift the jaw E9 to the right until itcontacts with the right-hand clamping jaw 26 and thus form a closure forthe mold 22, so that molten metal ejected into the mold will form ablank slug. The cam #35 is removable and in the present case it is soformed that during the first and second cycle of operation the left-handclamping jaw It remains in its normal position to the left and duringthe third and fourth cycle of operation the left-hand clamping jaw ismaintained against the right-hand clamping jaw 26 to form a closure forthe mold To permit the left-hand clamping jaw I9 to be free of theinfluence of the Geneva movement so that the machine will operate toproduce printing slugs alone, the lower arm of the jaw actuating lever41 is formed in two sections, the upper section 52 forming acontinuation of the upper arm of the jaw actuating lever, and the lowersection 53 being pivoted co-axially of the lever on a pin 54 andcarrying the aforementioned roller 45. The two sections 52 and 53 arecoupled together by means of a retractable spring pressed plunger (notshown) carried by the lower section 53 and engaging in a socket in theupper section 52. When the left-hand clamping jaw 19 is to be subjectedto the action of the cam 55, the plunger is seated in the socket butwhen the jaw I9 is to be freed from the influence of the cam, theplunger is withdrawn from the socket. When the lever is thusdisconnected from the cam, the lower roller carrying section will be inthe position shown by the dotted lines (Fig. 1) and will be free tovibrate idly about the axis without imparting motion to the leveritself. The details of the casting of printing slugs and blank slugs arefully shown and described in U. S. Patent No. 1,955,621, and furtherexplanation thereof is not deemed necessary. The improved equipment isintended to adapt such machines to automatically cast a plurality ofduplicate printing slugs, such as shown by (c) Fig. 3, or a plurality ofduplicate printing slugs and a plurality of blank slugs, such as shownby (f) and (g) respectively in Fig. 3; and to separate and stack theduplicate slugs as they are delivered into the storage galley.

All the mechanism necessary for the control of the elements involved inthe casting of duplicate printing slugs or duplicate printing slugs andblank slugs are as well as the separating and stacking of the duplicateslugs, in accordance with the preferred embodiment of the presentinvention, actuated by an element of the machine which movesperiodically during a machine cycle of operation through the medium ofcontrol mechanism which is capable of being set selectively to cause themachine to operate continuously through any predetermined or desirednumber of casting cycles.

As stated heretofore, the mechanism, among other uses, is of particularvalue in the production of duplicate printing slugs or duplicate printinslugs and blank slugs such as those used in advertising or telephonebook work, and for this reason in describing the arrangement formaintaining the machine in continuous operation throughout a pluralityof cycles, a condition has been selected, by way of illustration,wherein the machine is operated continuously for two cycles withoutinterruption to produce duplicate printing slugs or for four cycleswithout interruption to produce duplicate printing slugs and In eithercase the machine cycles are inaugurated when the operator raises theassembler !3 wherein a line has been composed to permit the line to betransferred to the first elevator or line transporter l8 which thereupondescends to present the line to the mold 22 to cast a printing slug. Thetransporter I8 thereafter ascends in the usual manner, but at this phaseof the cycle when the control mechanism is set to complete two cycles ofoperation means are rendered active to automatically inaugurate a secondcycle of operation; to prevent the transfer of the composed line fromthe transporter l8 so that the same line is again presented to the mold22 during the second cycle to produce a duplicate printing slug, and toeffect the operation of a slug separating gate which acts to separatethe duplicate printing slugs as they descend into the galley 26. At thisphase of the cycle when the control mechanism is set to complete fourcycles of operation means are rendered active to automaticallyinaugurate a second, third and fourth cycle of operation; to prevent thetransfer of the composed line from the transporter 18 so that the sameline is again presented to the mold during the second cycle to produce aduplicate printing slug; to render the line transfer preventing meansinactive to permit the line to be transferred from the transporter l8after the duplicate slug has been cast during the second cycle so thatblank slugs may be cast during the third and fourth cycles, and toefiect the operation of the slug separating gate s that duplicate slugsare separated as they descend into the galley.

The control mechanism is adapted and arranged to be operated by the moldwheel 23 and, as shown moreclearly in Figs. 2 and 5, it includes a foreand aft slide rod 51 which is journaled in bearings 58 and 59 carried bya bracket 60 secured to the main frame of the machine. The slide rod 5'!is provided with a finger 62 having an adjusting screw 68 positionedtherein and with an operating handle 63 by means of which the rod may berocked to carry the adjusting screw into and out of the path traveled bythe mold wheel 23 as it advances from its rotating position. The sliderod 51 is also provided with an arm 64 on which a pawl 65 is pivotallyconnected as by a pin 66. The pawl 65 is maintained in engagement with aratchet wheel 10 by means of a spring I I, one end of which is securedto the inner end of the pawl 65 and the other end of which is secured toa link 12 carried by the pin 66 on which the pawl 65 is pivotallymounted. The ratchet wheel is mounted on the upper end of the shaft 36which is rotatably mounted in the lugs or bearings 31 and 38 instead ofbeing fixedly mounted therein as it usually is. When the mold wheel 23advances preparatory to the slug casting operation it engages theadjusting screw 68 carried by the finger 62 and so forces the slide rod5'! and the pawl 55 outwardly against the action of a spring 6|positioned about the slide rod between the handle and the front bearing.As the pawl 65 moves outwardly it rotates the ratchet wheel 16 and thevertical shaft 36 through a partial turn. As the mold wheel 23 iscarried back to its rotating position after the casting operation theslide rod 5! and the pawl 65 are forced back to their initial positionby the action of the spring 61. In like manner when the mold wheel 23advances preparatory to the slug electing operation theshaft 36 is givena second partial turn. The extent of the partial turn which the shaft 36makes each time the mold wheel '23 moves forward from its rotatingposition depends on the stroke of the pawl 65, and that may be adjustedby varying the position of the adjusting screw 58 and its lock nut 59 inthe finger 62 and the position of the lock nut B? on the threaded outerend of the slide rod.

In the present embodiment of the invention, the ratchet wheel isprovided with sixteen teeth and the stroke of the fore and aft slide rod51 is adjusted so that the pawl 65 engages successive teeth on theratchet wheel as it is carried forward during the slug casting and theslug ejecting operations. Under such conditions, the shaft 36 is rotatedone-sixteenth of a revolution each time the mold wheel 23 advances fromits rotating position.

The means desirably employed for automatically inaugurating the secondcycle of operation necessary to produce duplicate printing slugs and thesecond, third and fourth cycles of operation necessary to produceduplicate printing slugs and two blank slugs comprises the clutchcontrol bar 3! which normally is operated manually by the operator. Whenthis clutch control bar is in its neutral or inoperative position theclutch is disengaged from the main drive shaft and the machine is idle.When, however, the clutch control bar is swung forward the clutch,through mechanism heretofore described, is rendered active and a machinecycle of operation is inaugurated. The actuation of the clutch controlbar to automatically inaugurate the second cycle of operation to producea duplicate printing slug is effected by the control mechanism throughthe medium of a lower clutch control cam 15 which is secured to theshaft 36 and the actuation of the clutch control bar to automaticallyinaugurate a second, third and fourth cycle of operation to produce aduplicate printing slug and two blank slugs is effected by the controlmechanism through the medium of an upper clutch control earn it which isalso secured to the shaft 36, and to render either of these control camseffective a selector mechanism is provided.

- As shown more clearly in Figs. 2 and 8, the selector mechanismcomprises a roller l! which is adapted and arranged to be maintained incontact with the lower cam 15 when two continuous machine cycles ofoperation are desired and with the upper cam FE when four continuousmachine cycles of operation are desired.

To permit the roller T! to be switched from engagement with one cam toengagement with the other cam as well as to provide means for lockingthe roller i! in engagement with either of the cams, it is mounted on apin journaled in the offset bifurcated inner end of a fore and aft sliderod 19. The outer end of the slide rod 19 is journaled in the outer wallof a housing member 80 which is secured as by a screw 8| and dowel pins82 and 83 to the lower side of the clutch control bar 3|, and the innerend of the slide rod '59 has a bearing bushing 84 which is journaled inthe inner wall of the housing member 88. A spring 86 which is relativelystrong as compared to the usual clutch control bar retractive spring ispositioned about the fore and aft slide rod '19 within the housingmember 80, and the bearing bushing 84 is provided with a groove 81 whichengages a guiding pin 88 extending inwardly from the housing member andwhich extends radially around one-half of the rear end of the bushing 86and then forwardly along opposite sides thereof. A pair of lock nuts 89are in threaded engagement with the outer end of the fore and aft sliderod 19 and are so positioned thereon as to prevent the relatively strongspring 86 from forcing the roller 71 into excessive frictionalengagement with the cams. Normally, when the clutch control bar 3| is inits neutral or inoperative position the roller ll is positioned adjacenta low segment on a cam. Under such conditions when a high segment iscarried in front of the roller, the roller, the fore and aft slide rod79, housing member 80 and the clutch control bar 3! are forced outwardlyas a unit against the action of the usual clutch control bar retractivespring rather than the slide rod '19 being forced outwardly through thehousing member 80 against the action of the relatively strong spring 86.To aid in the manipulation of the fore and aft slide rod 19 whentransferring the roller 1? from one cam to the other a knob 90 issecured, as by a pin 9|, to the outer end thereof. When making thetransfer of the roller 1! from one clutch control cam to the other, asfor example, when transferring from the upper clutch control cam 16 tothe lower clutch control cam 15, the slide rod 19 is pulled outwardlyagainst the action of the spring 86 until one end of the radial portionof the groove 81 is against the pin 88, then it is rotated a half turnor until the other end of the radial portion of the groove is againstthe pin and then it is released. When released the slide rod 19 isforced inwardly by the action of the spring 86 until the lock nuts 89are against the outer wall of the housing member 80 and as a result thepin 88 is now positioned in the oppositely disposed forwardly extendingportion of the groove 87 thus locking the roller H in front of the lowerclutch control cam 15. When making this transfer from the upper to thelower control cam it is obvious that the hand lever 34 must be lookedback otherwise the clutch control bar 3| would be pulled forward intooperative position instead of the slide rod 19 being pulled outwardlyagainstthe action of the spring 86. In this connection, it is also to benoted that the spring operated slide rod 19 permits the machine to bestopped or restarted at will by the manipulation of the hand lever 34 inthe usual manner.

As clearly shown in Fig. 11, the upper clutch control cam 16 which isutilized to automatically inaugurate the three additional cycles ofoperations necessary to produce duplicate printing slugs and two blankslugs is divided into two alternate operative or high segments 95 andtwo alternate inoperative or low segments 95. Prior to the beginning ofthe recasting operation the position of the upper clutch control cam '16is as shown in (a) of Fig. 11, that is, the roller 'l'l engages a lowsegment 96 of the cam. Under such conditions, the clutch control bar 34is held in its neutral inoperative position by the usual control clutchbar retracting spring. As the mold wheel 23 moves forward prior to theline casting operation, the shaft 36, as heretofore explained, isrotated through one-sixteenth of a revolution by the action of the pawl85 and ratchet wheel 76. As the shaft 36 rotates through one-sixteenthof a revolution the clutch control cam 16 is rotated accordingly and asa result the cam is carried in front of the roller 1'! half way betweena low segment 96 and the next adjacent high segment 95. Under suchconditions, the clutch control bar 35 is forced outwardly against theaction of the clutch control bar retracting spring one-half the distancenecessary to actuate the clutch, this portion of the cam being shaped toprovide a seat for the roller I? when in this position. When the moldwheel 23 again advances during the first cycle to eject the slug, theshaft 36 is again rotated through one-sixteenth of a revolution and as aresult the front end of the next high segment 95 of the cam is carriedin front of the roller 57 as shown in (b) Fig. 11, thereby forcing theclutch control bar 3i outwardly to its operative position to actuate theclutch and thus automatically inaugurate a second cycle of operation. Inlike manner, the two forward movements of the mold wheel 23 to cast andeject the slug during the second cycle of operation rotates the shaft 36and the associated clutch control cam I6 through one-eighth of arevolution, thereby carrying the center of a high segment 95 of the camin front of the roller I! as shown in (c) Fig. 11, and as a result theclutch control bar 3! is maintained in its operative position and athird cycle of operation is automatically inaugurated. The two forwardmovements of the mold wheel 23 during the third cycle of operationscarry the rear end of a high segment 95 of the cam in front of theroller ll as shown in (d) Fig. 11, thereby maintaining the clutchcontrol bar 3I outwardly in its operative position to automaticallyinaugurate a fourth cycle of operation. The two forward movements of themold wheel 23 during the fourth cycle of operation, however, restoresthe cam to its initial position as shown in (a) Fig. 11, that is, a lowsegment 96 of the cam is in front of the roller 11, thereby permittingthe clutch control bar 3I to return to its inoperative position underthe influence of the usual clutch control lever retractive spring toautomatically stop the machine at the end of the fourth cycle ofoperation.

As shown more clearly in Fig. 8, the lower clutch control cam 15 whichis utilized to automatically inaugurate the second cycle of operationnecessary to produce duplicate printing slugs alone comprises fouralternate high or operative segments 91 and four alternate low orinoperative segments 98. At the beginning of the recasting operationwhen it is desired to produce a single duplicate printing slug, theroller 11 is maintained against the low segment 98 of the lower clutchcontrol cam I5. Under such conditions, the clutch control bar 3I is heldin its neutral inactive position by the usual clutch control barretractive spring. As the mold wheel 23 moves forward prior to the linecasting operation during the first cycle of operation the shaft 35 andthe lower clutch control cam 15 associated therewith are rotated throughone-sixteenth of a revolution, as explained heretofore, thereby carryingthe lower clutch control cam I5 mid-way between a low segment 08 and thenext adjacent high segment 91 in front of the roller 11, and, as aresult, the clutch control bar 3I is forced outwardly onehalf thedistance necessary to put it in operative position. As the mold Wheel 23again advances during the first cycle to eject the slug, the shaft 35and the lower clutch control cam "I5 are again rotated throughone-sixteenth of a revolution, thereby carrying a high or operativesegment 01 of the cam in front of the roller TI, thus forcing the clutchcontrol bar 3| outwardly to its operative position to automaticallyinaugurate a second cycle of operation to produce a duplicate printingslug. In like manner, the two forward movements of the mold wheel 23during the second cycle of operation carry the next low segment 98 ofthe cam in front of the roller TI, thus permitting the clutch controlbar 3| to be retracted to its inoperative position to automatically stopthe machine at the end of the second cycle of operation.

While clutch control ca ms which permit two or four cycles of operationto be automatically started are shown and described, it is obvious thatby changing the shape of the cams and the length of the stroke of thefore and aft slide rod 51 any desired number of cycles of operation maybe automatically inaugurated.

When the machine is set to automatically inaugurate the second machinecycle of operation to produce a duplicate printing slug it is essentialthat the usual transfer of the composed line from the line transporterbe prevented during the first machine cycle of operation andpermittedduring the second machine cycle of operation, and when themachine is set to automatically inaugurate a second, third and fourthmachine cycle of operation it is also essential that the usual transferof the composed line from the line transporter be prevented during thefirst machine cycle of operation and permitted during the second machinecycle of operation so that a duplicate printing slug may be cast duringthe second cycle and blank slugs may be cast during the third and fourthcyclesof operation. In the present embodiment of the invention thetransfer of the line from the line transporter during the first of aseries of machine cycles of operation is prevented by arresting theascent of the line transporter I8 so that the stop member 21 carried bythe transporter I8 is in the path of the stop member 28 carried by theslide 29. The ascent of the line transporter is arrested in thisposition by the control mechanism through the medium of a linetransporter control cam I00 which is secured as by a pin IOI, to thelower end of the shaft 36. A roller I02 mounted on a pin in thebifurcated inner end of a bell crank lever I04 is maintained in contactwith the line transporter control cam I00 by a spring I05, one end ofthe spring being secured to the lever I04, as by a pin I06, and theother end of the lever being secured, as by an eye bolt' I01, to abracket I08 which is secured to the main frame of the machine. The bellcrank lever I04 is pivotally mounted on a pin I00 which is also carriedby the bracket I08, and the outer end of the lever is provided with apin IIO which extends downwardly from the lower face thereof and engagesa slot III in the right-hand end of the stop plate H2. The left-hand endof the stop plate H2 is loosely secured to the main frame of the machineby a stud I I3, the opening I I4 through which the stud H3 passes beingelongated to permit lateral movement of the stop plate II2 under theinfluence of the bell crank lever I04. The pin III) carried by the outerend of the bell crank lever I04 is maintained in the slot I I I in theright-hand end of the stop plate I I2 when recasting is desired by meansof a face plate I I5 which is secured to the stop plate I I2 by a screwI I6. As shown more fully in Fig. 10, the line transporter control camI00 is provided with four alternate high or operative segments I20 andfour alternate low or inoperative segments I2I, and as shown in (a) Fig.10, the cam is so positioned on the shaft 36 that at the beginning ofthe first of a series of machine cycles of operation the roller I02 isagainst a low segment I2I and at the beginning of the rise leading to anadjacent high segment I20. Under such conditions when the mold wheel 23advances preparatory to the slug casting operation during the firstmachine cycle of operation the shaft 32 is rotated through one-sixteenthof a revolution and a high segment I20 of the cam I00 is rotated infront of the roller I 02, the roller under such circumstances bearingthe relation to the cam indicated by the dotted lines in (a) Fig. 10.When a high part of the cam I00 is rotated in front of the roller I02,the inner end of the bell crank lever I04 is forced outwardly againstthe action of the spring I05 and as a result the lever I04 is rotatedabout the pivot pin I09, thereby forcing the outer end of the bell cranklever I04 to the left. As the outer end of the bell crank lever I04 isforced to the left the stop plate II2 which is connected thereto islikewise forced to the left into the path of an adjusting screw II'Icarried by a projecting lug IIB on the lower end of the line transporterI8. The position of the adjusting screw II! is such that when it engagesthe stop plate H2 in its upward travel, the stop member 21 carried bythe line transporter I8 is positioned in the path of the stop member 28carried by the transverse slide 29, thereby preventing the normaloperation of the slide 29 to transfer the line from the transporter I8.As the mold wheel 23 again advances during the first cycle to eject theslug, the shaft 36 and line transporter control cam I00 are againrotated through onesixteenth of a revolution so that after thecompletion of the first cycle of operation the roller I02 bears therelation to the cam I00 as shown in (b) Fig. 10, that is, the rear endof a high segment I20 of the cam is in front of the roller, consequentlythe stop plate H2 is maintained in its operative position. As the moldwheel 23 advances prior to the slug casting operation during the secondcycle of operation, the shaft 36 and the line transporter control camI00 are again rotated through one-sixteenth of a revolution, therebycarrying the beginning of a low segment I2I in front of the roller I02and as a result the stop plate H2 is forced to the right to its inactiveposition by the bell crank lever I04 under the influence of the springI05, thus permitting the line transporter I8 to ascend to its uppermostor line transfer position after the duplicate slug has been cast. As themold wheel 23 advances to eject the slug during the second cycle ofoperation, the shaft 36 and the line transporter control cam I00 areagain rotated through onesixteenth of a revolution, thereby carrying therear end of a low segment I2I against the roller I 02 so that at the endof the second cycle of operation the cam I00 bears the relation to theroller I02 as shown in (c) Fig. 10, that is, the rear end of a lowsegment I2I of the cam is in front of the roller, consequently the stopplate H2 is maintained in its inoperative position. Then as the moldwheel 23 moves forward prior to the line casting operation during thethird cycle of operation the shaft 36 and the line transporter controlcam I00 are again moved through one-sixteenth of a revolution and thefront part of the next adjacent high segment I20 of the cam is carriedin front of the roller I02. As explained heretofore, the movement of ahigh segment I20 of the cam I00 in front of the roller I02 forcesthestop plate I I2 to the left to prevent the ascent of the linetransporter I8 to its uppermost or line transfer position. As the moldwheel 23 again advances during the third cycle to eject the slug, theshaft 36 and the line transporter control cam I00 are again rotatedthrough one-sixteenth of a revolution, thereby carrying the rear portionof this high segment I20 in front of the roller I02 so that at the endof the third cycle of. operation the cam I00 bears the relation to theroller I02 as shown in (d) Fig. 10, that is, the rear end of a highsegment I20 is against the roller I02, consequently the stop plate H2 ismaintained in its operative position. As a result of the first forwardmovement of the mold wheel 23 during the fourth cycle of operation theshaft 36 and the line transporter control cam I00 are again rotatedthrough one-sixteenth of a revolution thereby carrying the beginning ofa low or inoperative segment I2I in front of the roller and as a resultthe stop plate H2 is retracted to the right to its inoperative position.The second forward movement of the mold wheel 23 during the fourth cycleof operation rotates the shaft 36 and the line transporter control camI00 through another one-sixteenth of a revolution so that at the end ofthe fourth cycle of operation the cam bears its initial relation to theroller I02 such as shown by (a) Fig. 10, that is, the rear end of a lowsegment I2I is in front of the roller, consequently the stop plate I I2is maintained to the right in its inoperative position. It is thus seenthat the transporter I8 is prevented from ascending to its uppermost orline transfer position after each alternate cycle of operation, therebypermitting duplicate printing slugs to be produced when the machine isset to complete two machine cycles of operation or duplicate printingslugs and duplicate blank slugs to be produced when the machine is setto complete four machine cycles of operation.

The improved galley 26 is inclined and is provided with a plurality ofcompartments for holding the slugs in separate columns in order thatduplicate slugs may be kept apart, and thus obviate the necessity ofsorting them out by hand later on. In the present embodiment, as shownin Figs. 2, 4 and 5, the galley 26 is divided by a partition into upperand lower compartments I23 and I24 respectively, into which the slugsare selectively delivered as they are ejected from the knife block 24,and in which they are progressively advanced by the stacking lever I25.The means for determining the column into which the slugs are to bestacked, comprises a movable gate I26 positioned in line with thedischarge end of the chute into which the slugs are ejected from themold. When the gate I26 is in the lower position as shown in full linesin Fig. 2, the ejected slug will, of course, be stacked in the uppercompartment I 23, whereas when the gate is swung upwardly as shown indotted lines, the ejected slug is stacked in the lower galley I24.

The operation of the gate I26 to separate duplicate slugs is effected bythe control mechanism through the medium of a slug separating cam 121which is secured to the upper end of the shaft 36. Since it is desiredto separate alternate slugs, it is essential that the gate I26 beoperated at the end of each complete cycle of operation and for thisreason, the cam I2'I as fully shown in Fig. 12 is provided with fouralternate high or operative segments I30 and four alternate low orinoperative segments I3I. The cam I21 engages a roller I32 which isjournaled on a horizontal shaft I33 mounted in the bifurcated inner endof a rocker arm I28, the rocker arm being pivoted on a shaft I34 mountedin the bifurcated upper end of a bracket I35 carried by the main frameof the machine. The gate I26 is detachably mounted as by a stud I29 tothe outer end of the rocker arm I28, and the rocker arm is pivotallymounted off center so that the weight of the outer end of the rocker armmaintains the roller I32 in contact with the face of the cam I21. Asshown more fully in (a) Fig. 12, prior to the beginning of the recastingoperation, the roller I32 engages a low segment I3I of the cam I2! andthe gate I26 is lowered. The two forward movements of the mold wheel 23during the first cycle of operation rotates the shaft 35 and theassociated slug separating control cam I27 through one-eighth of arevolution thereby carrying a high or operative segment I30 of the camI21 above the roller I32 as shown in (b) Fig. 12, and as a result theinner end of the rocker arm I28 is depressed and the outer end of therocker arm carrying the gate I 26 is raised thus permitting the slugcast during the first cycle to descend to the lower compartment I26wherein it is stacked by the stacking lever I25. The two forwardmovements of the mold wheel 23 during the second cycle of operationrotates the shaft 38 and the associated slug separating cam I27 throughanother one-eighth revolution, thereby carrying a low or inoperativesegment I3I above the roller I32 as shown in (c) Fig. 12, and as aresult the inner end of the rocker arm I2? is raised and the outer endof the rocker arm carrying the gate I23 is lowered so that the slug castduring the second cycle is stopped adjacent the upper compartment I23and is stored therein by the stacking lever I25. In like manner, the twoforward movements of the mold wheel 23 during the third cycle ofoperation carry a high or operative segment I30 of the cam I2'I abovethe roller I32 as shown in (d) Fig. 12, so that the slug cast during thethird cycle descends to the lower compartment I 24 and is stackedtherein by the stacking lever I25. The two forward movements of the moldwheel 23 during the fourth cycle carry the cam I27 back to its initialposition as shown in (a) Fig. 12, that is, a low or inoperative segmentI3I of the cam I2? is carried above the roller I32 so that the slug castduring the fourth cycle is stacked in the upper compartment I23.

In the operation of the machine, when it is desired to cast duplicateslugs, the recasting con trol mechanism is first adjusted to cast thedesired number of slugs, that is, if one duplicate printing slug and twoblank slugs are to be cast, the roller TI is rotated into engagementwith the upper clutch control cam I6, the slotted righthand end of thestop plate H2 is brought into engagement with the pin II3 carried by theouter end of the bell crank lever I34 and the finger 32 is rotated intooperative position in front of the mold wheel 23. The composed line isthen delivered to the line transporter I8 and the machine started in theusual manner. At the beginning of the cycle of operation, the linetransporter control cam H10, the upper clutch control cam I6 and theslug separating control cam I2! are in their normal position as shown in(a) Figs. 10, 11 and 12 respectively, that is, low or inoperativesegments are in front of the rollers I02, 'I'! and I32 respectively andthe stop plate II2 is to the right or inoperative position, the clutchcontrol bar SI is in its neutral inoperative position and the slugseparating gate I25 is in its lowered position. I

As a result of the two forward movements of the mold wheel 23 during thefirst cycle of operations, the stop plate IE2 is moved to its activeposition, thus preventing the line being transferred from the firstelevator or line transporter I8 during the first cycle of operationssothat the same line is again presented to the mold 22 during the nextcycle of operations to produce a duplicate printing slug, the clutchcontrol bar 3I is forced outwardly to its active position, thusautomatically inaugurating a second cycle of operation and the gate I26is raised thus permitting the printing slug cast during the first cycleto be stored in the lower compartment I24. As a result of the twoforward movements of the mold Wheel 23 during the second cycle ofoperation, the stop plate H2 is returned to its inoperative positionthus permitting the line transporter I8 to ascend to its uppermost orline transfer position; the clutch control bar 3| is maintained in itsoperative position to automatically inaugurate a third cycle ofoperation and the gate I26 is lowered, thus permitting the duplicateprinting slug cast during the second cycle to be stored in the uppercompartment I23. Since the first elevator or line transporter I8 ispermitted to ascend to its uppermost or line transfer position, duringthe second cycle of operation, the line is transferred therefrom by theslide 29 into the upper transfer channel 30 from which the matrices arereturned to their respective magazines. At the end of the second cyclethe left-hand vise jaw I9 is automatically moved to the right intoengagement with the right-hand vise jaw 28 to form a closure for themold 22 by the Geneva movcment, as explained heretofore, so that a blankslug is cast during the third cycle. As a result of the two forwardmovements of the mold wheel 23 during the third cycle of operation, thestop plate I I2 is again moved to its operative position, the clutchcontrol bar 3I is maintained in its operative position to automaticallyinaugurate a fourth cycle of operation and the gate I26 is lowered topermit the blank slug cast during the third cycle to be stacked in thelower compartment I24 adjacent the printing slug cast during the firstcycle of operation. In the present case, of course, the movement of thestop plate II2 to its operative position is immaterial since a blankslug is cast. At the beginning of the fourth cycle of operation theleft-hand vise jaw I9 is again moved to the right into engagement withthe right-hand vise jaw 20 to form a closure for the mold 22 so that ablank slug is also cast during the fourth cycle of operation. As aresult of the two forward movements of the mold wheel 23 during thefourth cycle of operation, the stop plate H2 is returned to its normalinactive position, the clutch control bar 3! is returned to its neutralinoperative position to automatically stop the machine at the end of thefourth cycle of operation and the gate I26 is lowered, thus per- 7mitting the blank slug cast during the fourth cycle of operation to bestacked in the upper compartment I 23 adjacent the printing slug castduring the second cycle of operation.

In the event two duplicate printing slugs are required the lower rollercarrying section of the jaw actuating lever 41 is moved out of contactwith the cam 45, as explained heretofore, to render the Geneva movementinoperative and the slide rod 5'! is rotated a half turn to bring theroller 11 adjacent the face of the lower clutch control cam I5. Thecomposed line is transferred to the first elevator or line transporterI8 and the first cycle of operations started in the usual manner. As aresult of the two forward movements of themold wheel 23 during the firstcycle of operation, the stop plate II2 is moved to the left to itsactive position, thereby prevent ing the line transporter I8 fromascending to its uppermost or line transfer position so that the sameline is again presented to the mold during the next cycle of operationto produce a duplicate printing slug; the clutch control bar Si isforced outwardly to its operative position, thereby automaticallyinaugurating a second cycle of operation and the gate I26 is raisedthereby permitting the printing slug cast during the first cycle to bestacked in the lower compartment I24. As a result of the two forwardmovements of the mold wheel 23 during the second cycle of operation thestop plate H2 is retracted to the right to its inoperative position thuspermitting the line transporter I8 to ascend to its uppermost or linetransfer position; the clutch control bar 3| is moved to its neutralinoperative position to permit the machine to automatically stop afterthe completion of the second cycle of operation and the gate I26 islowered, thereby permitting the slug cast during the second cycle to bestacked in the upper compartment I23.

If one printing slug and one blank slug is desired the roller I1 isrotated into engagement with the lower clutch control cam I5 so as topermit the machine to complete two cycles of operation beforeautomatically coming to rest, the cam 45 on the Geneva plate 48 ischanged so that the left-hand vise jaw I9 is moved to the right to closethe mold during alternate cycles of operation and the stop plate H2 isdisengaged from the outer end of the bell crank lever I04 and is rotatedto the position indicated by the dotted lines in Fig. 5, so that it isnot carried into the path of the adjusting screw II! on the projectinglug I I8 by the action of the first elevator control cam I00. Under suchconditions, a printing slug is cast during the first cycle of operationand a blank slug is cast during the second cycle of operation. In thiscase it is not necessary to separate the slugs as they are cast,consequently the stud I 29 which secures the gate I22 to the outer endof the rocker arm I24 is loosened and the gate is rotated into inactiveposition, thereby permitting the printing slugs and blank slugs to bestacked adjacent one another in the lower com- Dartment I24.
